What solvent/cleaner to remove duct tape adhesive from acrylic tub?

I foolishly used duct tape to secure a drop cloth while installing mud walls in my tub alcove. The tape left some adhesive goo. What solvent or cleaner can I used that won't damage the acrylic finish?

I'm a big fan of Goof-Off, but this is the chemical xylene, which I think is a solvent for acrylic and would damage the tub. In my arsenal I also have mineral spirits, turpentine and acetone. HD/Lowe's is not far so I can run out and get something else if needed.

I use my wife's nail polish remover (acetone) on surfaces that I don't care about, but I also use Goo Gone and Oops!, which are basically similar citrus-based stuff, for tub/shower and sink surfaces.
Goo Gone will even instantly remove clear silicone caulk off of your hands better than gasoline, which is what I used to use years ago.
That stuff is amazing.
